Specification of Letters Patent.

Patented Dec. '7, 1915.

Application filed August 21, 1915. Serial No. 46,746.

To all whom it may concern:

Be it known that I, ALBERT MA'rtrsoN, a subject of the King of Sweden,residing at (lured, Krokstad, Sweden, have invented certain new anduseful Improvements in Scissors, of which the following is aspecification.

The present invention relates to scissors and more particularly to suchas are used by barbers. I

T he invention resides in an improvement in such scissors which makes itpossible to vary, at will and without any special adjustments, thenumber of cuts of the blades for each closing of the handles. Theadvantage of this construction will readily be understood, as cuttingwith these scissors is less tiring for the operator than when 4 usingordinary scissors.

One embodiment of the present invention is illustrated in theaccompanying drawing where Figure 1 shows a plan view of the scissorsclosed; Fig. 2 is a similar view with the scissors open; Fig. 3 is aside view of Fig. 1 partly in section, and Fig. l is a ratchet wheelhaving a greater number of teeth to what has been shown in Figs. 1 and2.

The scissors have a short blade 10 and a long one 11 which are journaledby means of a pin or screw 12 secured in the long blade. Attached to thescrew at one end and to the short blade 10 at the other end 13 is aspiral or other suitably-shaped spring 13, which tends to close theblades. The continuation of the large blade forms one handle with loops23, while a short handle with a loop 22 is fulcrumed on a journal 18threaded in the long handle. On the same journal. is mounted to revolve,a ratchet member having teeth 15 meshing with a tooth 14.- formed on therear end of the short blade 10. This ratchet member is also pro- \idedwith another set of teeth 16 011 a smaller diameter and facing inopposite direction to teeth 15.

The connection between the hub part 17 and the short handle and loop 22,is offset, so that the shoulder formed is facing the teeth 16. In arecess 21 in this handle a plunger 19 actuated by a compression spring20 is mounted to slide radially and engage with the teeth 16. There maybe the same number of teeth 15 as teeth 16 or there may be more of theteeth 15, but always an exact multiple thereof depending on how small orlarge strokes are required, and the ratchet member may therefore be madeexchangeable and two or three with different num ber of teeth may besupplied with each. pair of scissors.

As illustrated in the accompanying drawing, the same number of teeth 15and 16 are provided. To vary the number of strokes of the blades, thehandles will then have to be opened a different amount. If for instance,the handle is opened only slightly so that the plunger only passes overone tooth 16, then, upon closing the handle, the plunger will turn theratchet member in the direction of the arrow 11 and the short blade willbe forced open once by a tooth 16 as seen in Fig. If on the other hand,the handle 22 has been opened far enough for the plunger to pass twoteeth 16, then, upon again closing the handle, the blade will be openedand closed twice. It is obvious that the tooth 14 serves as a stop tohold the ratchet member from turning during the opening of the handle.

While the form of the invention herein shown and described is what isbelieved to be the preferred embodiment thereof, it is nevertheless tobe understood that minor changes may be made therein without departingfrom the spirit and scope of the invention as claimed.

YVhat I claim as new is 1. In a pair of scissors, a blade with a, rigidhandle, a short blade journaled thereon, a short handle also journaledon the first blade and handle, and means interposed be tween. said shorthandle and short blade for opening and closing said short blade uponclosing said short handle, said means comprising a pawl and ratchetdevice ournaled coaxially with and actuated by said short handle, asecond ratchet device connected to the first and constructed to actuatesaid short blade.

2. In a pair of scissors, a blade with a rigid handle, a short bladejournaled thereon, a short handle also journaled on the first blade andhandle, a ratchet member mounted coaxially with said short handle, andhaving two sets of teeth facing in opposite directions, a springactuated pawl in said short handle engaging with one set of said teethfor turning said member upon the closing of the short handle, saidsecond set of teeth engaging with said short blade to open'it andseparate means tending to close the blade.

3. 111 a pair of scissors, a blade with a rigid handle, a short bladejournaled thereon, a short handle also journaled on the first blade andhandle, a ratchet member mounted coaxially with said short handle, andhaving two sets of teeth facing in opposite directions, a springactuated pawl in said short handle engaging with one set of said teethfor turning said member upon'the closing of the short handle, saidsecond set of teeth engaging with said short blade to'open it andseparate means tending to close the blade, the number of said second setof teeth being a. multiple of that of the first set of teeth, wherebysaid short blade will be made to open and close several times while theshort handle is being closed once.

4. In a pair of scissors, a blade with a rigid handle, a short bladejournaled thereon, a short handle also journaled on the first blade andhandle, a ratchet member mounted coaxially with said short handle, andhaving two sets of teeth facing in opposite directions, a springactuated pawl in said short handle engaging with one set of said teethfor turning said member upon the closing of the short handle; said shortblade being provided with a tooth meshing with said second set of teethand preventing any reverse turning of said member, a spring tending toclose the short blade, said ratchet member on being revolved by saidshort handle opening said short for turning said member upon the closingof the short handle; said short blade being provided with a toothmeshing with said second set of teeth and preventing any reverse turningof said member, a spring tending to close the short blade, said ratchetmember on being revolved by said short handle opening said short blade,a plurality of times for each closing of the short handle.

In testimony whereof I al'lix my signature.
